FOLDING BED.

SPECIFICATION forming part of Letters Patent No. 505,477, datedSeptember 26, 1893.

Application filed September 15, 1892. Serial No. 445,937. (No model.)

To all whom it may concern.-

Be it known that we, NIELs ODEGAARD and ,GOTFRED KUHNLE, citizens of theUnited invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

Reference is had to the accompanying d rawings, forming a part of thisspecification.

This invention relates to improvements in folding-beds, and consists ofcertain novel features in the general construction, combination, andarrangement of the several parts, as will be hereinafter set forth.

Figure 1 is a broken-away section on line 1, Fig. 2, looking in thedirection indicated by the arrow; the parts being represented in afolded position; Fig. 2, a broken-away trans verse section on line 2,Fig. 1; Fig. 3, a detached plan of one of the cam-plates in which thepivot-rollers have their hearing and movement. Fig. 4 is a similar viewto that illustrated in Fig. 1, with the difference that the parts areshown in their opposite or unfolded position; Fig. 5, a broken-awaysection on line 5,'Fig. 4..

In the drawings, A represents the inclosing case and B the side-rails ofthe bed proper.

To the respective inner sides of the case are rigidly secured companioncam-plates O; the location and position of which are illustrated inFigs. 1, 4 and 5. A plan or faceview of one of these plates is shown inFig. 3. These cam-plates are provided on their faces or bearing-sideswith the wide groove or pathway, a, curving from a horizontal to aperpendicular plane. The rim or inclosing border 01/, (shown in Figs. 3and 5, and indicated by dotted lines in Figs. 1 and 4,) forms a trackfor the pivot or movement-rollers, 0. the peripheries of which bearagainst the rim a, as shown in Fig. 5. These rollers are attached to theouter sides and head-ends of the bed-rails by the-axial-pins a Afriction washer a is interposed between the rollers andtheadjacentsurfaces of the rails, as shown in Fig. 5. The movement rollers arerecessed on their inner sides, as at (1 Fig. 5, so that the head-ends ofthe axial pins may be countersunk out of contact with the adjacentsurfaces of the cam-plates. The segment part, a of the cam-plates isremovable so that the folding or bed-part proper may be disengaged fromor connected with the inclosing case. The opposite positions of themovement-rollers are indicated by dotted lines in Figs. 1 and 4, showingthe bed, respectively, in a folded and unfolded position.

Companion track-bars, D, are secured to the respective inner sides ofthe casing by a pivot-bolt b. To the front ends of these bars arepivoted, as at b, the additional supporting-legs b When the bed isfolded, these legs fold parallel with the respective bars, (Fig. l) anddrop down to the supporting right-angle position (Fig. 4) when the bedis unfolded.

To the rear ends of the respective trackbars are attached weights, 17 ina suspended position by means of a ring 12 which permits of the weightsalways remaining in a vertical position and serves to keep this portionof the track in its proper position when folding up the bed. By thisarrangement the inclosing case may be of a less depth than the ordinaryform, and the supporting center moved farther out in the direction ofthe foot-end when the bed is unfolded.

The track-bars, D, are cut away at their back ends and are provided withthe beveled shoulders b The bars D are rigidly secured to the respectiveinner sides of the casing by a number of screws d. These bars arelocated in line with and form a continuation of the tracking-surface ofthe bars D. The joining ends of the track-bars D are beveled, as at d,to closely engage the correspondingly beveled shoulders b of the largertrack-bars, so that the track sections are kept in line when the bed isin its open position.

The tracking surface of the bars D is raised as at d so that when thebed is closed it will remain in a perpendicular position and not inclineoutwardly away from the case.

The companion rollers E are secured to the respective side-rails byaxial-pins d These rollers track on the bars D D.

The lower corner ends of the head-board F are pivoted, as at d, to therespective upper corners of the side rails. The upper corner ends ofthis head-board are provided with bearing-lugs 9 (Fig. 2), mounted onthe supporting-rod g, which extends from side to slde in the back partof the case. The rollers g are mounted on the respective ends of the rodg, and travel in rabbeted grooves 9 A transverse bar It is attached tothe rear side of the head-board and supports the usual counterweightsit.

Having thus described our invention, what We claim as new, and desire tosecure by Letters Patent, is I 1. In a folding-bed, the combination withthe inolosing case, of the companion trackbars pivoted thereto andadapted to assume a vertical or a horizontal position, the trackbars orsections rigidly secured to the case in line with the pivoted bars, thelegs pivoted to the front ends of the pivoted bars, and the weightssuspended from the rear ends of the latter bars, substantially as setforth.

2. In a folding-bed, the combination with the inclosing case, of thecompanion trackbars, pivoted thereto and adapted to assume a vertical orhorizontal position, the legs, pivoted to the front ends of said bars,and the weights, suspended from the rear ends thereof, 5

substantially as set forth.

3. In a folding-bed, the combination with the case, of the track-barspivoted to the respective inner sides thereof, the legs pivoted to thefront ends of said bars, the track-bars or sections rigidly secured tothe case in line with and forming a continuation of the pivoted bars,the side-rails and the rollers pivoted thereto and tracking on saidbars, substantially as set forth.

4. In a folding-bed, the combination with the case, of the cam-plateshaving a curved pathway therein, the side-rails, the movement-rollersmoving in the curved pathway of the camplates, the track-bars pivoted tothe case, the legs pivoted to the front ends of said bars, thetrack-bars or sections rigidly secured to the case, and the rollersattached to the side-rails and tracking on said bars, substantially asset forth.

In testimony whereof we affix our signatures in presence of twowitnesses.
